m=E/c2

This calculator is the inverse of the E=mc2 calculator. If mass can be annihilated and become kinetic energy,
then energy can become mass/matter, right? It takes a TON of energy to create just one teeny tiny little speck of mass,
but it can be done. Go ahead and type a value of energy, and transform it into a chunk or speck of matter.

Every gray pixel = 1 POUND of mass. The combined energy of the 2 nuclear
bombs dropped on Japan (Little Boy and Fat Man), could not even create 1 gram of matter.

The combined powers of the largest thermonuclear weapon detonated by the USA (Castle Bravo) and Russia (Tzar Bomba), could only create about 7
pounds of matter. This entire box contains 70,000 pixels, that means this entire box = 70,000 pounds of mass. That may seem like a lot, but it's very small. The Earth
is just a speck in space, too small to even be justified as even being a microscopic speck, how much of Earth's mass does this "giant" block of 70,000 pounds
represent? One millionth, billionth, or trillionth? One quadrillionth? One quintillionth? Close... it represents around 100 quintillionth of the Earth's
total mass, which itself is just a little speck of nothing floating in space. The amount of energy it took to create Earth, and the rest of the cosmos
is INCREDIBLY large.

note: Firefox and Apple Safari are able to populate the box with significant amounts of red instantly, but IE 7.0 lags.

This is a list of different masses that you can type in. Some of these figures are the actual mass of an object, while others are not the mass of the object,
but the mass that was annihilated by the object, such as a nuclear bomb.

This 1st section is grams, so all listed values are either the amount of grams annihilated (nukes) or how many grams its mass is (random objects).

~0.014 Megatons

The explosive yield of Little Boy, the first nuclear bomb dropped on Japan. ~0.0006517 grams of mass was destroyed.

~0.023 Megatons

The explosive yield of Fat Man, the second nuclear bomb dropped on Japan.

0.03 Megatons

The amount of energy in a paper clip (1.4 grams). That's right, there is more energy in just 1
paper clip than either of the nukes dropped on Japan.

1.07 Megatons

The amount of energy in a nickel (5 grams, 0.05 kg). There is more energy in a nickel, than Little Boy, Fat Man, and a paper clip combined!
This of course is only counted the KE (kinetic energy) released by the nukes, not their PE (potential energy), because they weight MUCH more
than a nickel does.

~13 Megatons

About the amount of energy the entire human population digests in a day.

~15 Megatons

The explosive yield of Castle Bravo, the largest nuclear bomb detonated by the US. 698 grams of mass was annihilated.

19.5 Megatons

The amount of energy that would be released if a pound of antimatter came in contact with you.

~50 Megatons

The explosive yield of Tzar Bomba, the largest nuclear bomb detonated in the world.

~3,700 Megatons

The energy released if the typical adult male (190 pounds) came in contact with his antimatter twin.

~105,000 Megatons

The energy generated by the entire world in 2003.

~100 Million Megatons

Estimated amount of energy released by the Dinosaur Killer Asteroid (Chicxulub).

~95 Billion Megatons

The amount of energy the Sun generates every second.

There are many things that contain potential energy. Sugar, gasoline, fat/oil, TNT, gun powder, ethanol/alcohol and propane all contain potential energy. When a molecule of sugar, gasoline, TNT or alcohol is DESTROYED or 'burned', it releases the potential energy. In other words, the potential energy is converted into kinetic energy.

Albert Einstein realized that mass itself, was a form of potential energy. This means that if mass is DESTROYED/ANNHILATED, then its potential energy will be converted into kinetic energy. Einstein constructed an equation that would figure out how much kinetic energy would be produced by destroying mass. This equation is E=mc^2. E is for energy and M is for mass. Energy equals mass times C squared. C stands for the speed of light which is an incredibly huge number. Which means that mass contains an incredibly large amount of energy.

At the very top of this window there is a place to type in an amount of mass. Try typing in your weight and see how much energy would be released if all the energy contained in your mass was released.
